Abstract
A fire door belongs to the technical field of a door comprises a perlite layer, which is characterized in that U-shaped steel frameworks which are fast inserted and matched with the perlite layer are arranged on the four side edges of the perlite layer, door panels which are composed of flame-proof panels are respectively matched on the inner and the external layer surfaces of the steel frameworks, the fire door has novel conception and reasonable structure, U-shaped steel frameworks are fast inserted and matched on the four side edges of the perlite layer, the processes of drying and carrying out the fire retardant treatment to fir frameworks are avoided, the flame-proof performance of the frameworks is guaranteed, simultaneously, the intensity of the door panels is increased, and the door panels have no gap, when in fire hazard, even if the flame-proof panels of a burning surface are burned through, fire also can not reach the flame-proof panels on the other side, thereby the fire resisting time of the fire door is greatly improved.
Description
Technical field
The utility model belongs to the gate technique field, is specially labeled door.
Background technology
The conventional wooden labeled door all adopts the China fir shelves as skeleton, inlay again between the China fir skeleton and fill out perlite, and the China fir skeleton reach fire protection requirement must be through the timber stoving flame treatment operation of drying again again, therefore a lot of fire-proof wooden doors are in process of production on the market, because the moisture content height in the timber causes fire retardant fully not absorb or because the time that the nervous wood fire retardant of production task soaks is not enough, this all directly has influence on the fire resistance period of labeled door; Fill out in the perlitic process at edge in addition, because between China fir skeleton and the perlite all is plane contact, contact surface can produce certain slit, when breaking out of fire, after big fire will be burnt by one deck PLASTIC LAMINATED of fiery face, fire will be directly from scurrying the another side of door between the slit, thereby shortened fire resistance period greatly, these have all caused the qualification rate of labeled door in the market on the low side.
The utility model content
At the above-mentioned problems in the prior art, the purpose of this utility model is to design the technical scheme that the long labeled door of a kind of fire resistance period is provided, and its fire resistance is good, and the bulk strength height.
Described labeled door comprises the pearl rock stratum, it is characterized in that pearl rock stratum four side all is provided with the U-shaped steel frame of inlaying close-fitting with it, and is equipped with PLASTIC LAMINATED formation door-plate respectively on the outer layer surface within it.
Described labeled door is characterized in that the PLASTIC LAMINATED external surface is equipped with decoration panel.
Described labeled door is characterized in that the door-plate four side is provided with and the edge cover strip of its clamping close-fitting.
Described labeled door is characterized in that the pearl rock stratum is by two concavo-convex being spliced to form of perlite.
Described labeled door is characterized in that being equipped with in the pearl rock stratum by two L shaped shelves bars and is spaced the Z-shaped crosspiece that constitutes.
Described labeled door is characterized in that door-plate is connected by fire prevention hinge and doorframe, is provided with fire barrier in the doorframe.
Described labeled door is characterized in that being provided with on the door-plate Fire-proof lock.
Described labeled door is characterized in that being provided with on the door-plate door closer.
Described labeled door is characterized in that the inboard notch of doorframe place is equipped with the fire proof seal bar.
Above-mentioned labeled door, novel, rational in infrastructure, pearl rock stratum four side is all inlayed close-fitting the U-shaped steel frame is set, and has removed the China fir skeleton from and need dry the operation of carrying out flame treatment again, has guaranteed the fire resistance of skeleton, has also increased the intensity of door-plate simultaneously; There is not any slit in door-plate, and during breaking out of fire, even burnt by the PLASTIC LAMINATED of fiery face, fire can not scurried on the another side PLASTIC LAMINATED at once yet, has improved the fire resistance period of labeled door greatly.

Among the figure: 1-door-plate, 2-fire prevention hinge, 3-doorframe, 4-Fire-proof lock, 5-fire barrier, 6-edge cover strip, 7-U shape steel frame, 8-Z shape crosspiece, 9-decoration panel, 10-PLASTIC LAMINATED, 11-pearl rock stratum, 12-fire proof seal bar, 13-door closer.
The specific embodiment
The utility model is described in further detail below in conjunction with Figure of description:
As shown in the figure, pearl rock stratum 11 four sides all are provided with the U-shaped steel frame 7 of inlaying close-fitting with it, and are equipped with PLASTIC LAMINATED 10 formation door-plates 1 respectively on the outer layer surface within it, and PLASTIC LAMINATED 10 external surfaces can also be equipped with decoration panel 9.Pearl rock stratum 11 is by two concavo-convex being spliced to form of perlite, and splicing place does not produce the slit, and during breaking out of fire, even burnt by the PLASTIC LAMINATED 10 of fiery face, fire can not scurried on the another side PLASTIC LAMINATED 10 at once yet, has improved the fire resistance period of labeled door greatly.Laterally be equipped with in the pearl rock stratum 11 by two L shaped shelves bars and be spaced the Z-shaped crosspiece 8 that constitutes, L shaped shelves bar is spaced in the time of can avoiding breaking out of fire and conducts heat mutually, and L shaped shelves strip adoption cold-reduced sheet is made, and has further improved the intensity of door-plate 1.The edge cover strip 6 of door-plate 1 four side setting and its clamping close-fitting is tightened edge cover strip 6 and U-shaped steel frame 7 mutually with screw, prevents that PLASTIC LAMINATED 10, decoration panel 9 from coming unstuck with U-shaped steel frame 7.The edge cover strip 6 general wooden edge cover strips that adopt through flame treatment also can adopt through other material or the incombustible material of flame treatment and make.Fire-proof lock 4, door closer 13 are set on the door-plate 1, and door-plate 1 is connected with doorframe 3 by fire prevention hinge 2.Fire barrier 5 is set in the doorframe 3, and doorframe 3 inboard notch places are equipped with fire proof seal bar 12, and during breaking out of fire, fire proof seal bar 12 expanded by heating are blocked the crack between a door and its frame between doorframe 3 inboard notches and the door-plate 1, prevent that fire from scurrying the another side of door.
